I've been following this guy for over a year now on social media and is probably one of the best people to turn to to advice in regards to fitness and weightloss. Having just joined his online program (JSA academy) as well, I have nothing but good things to say about the man. He cuts through all the rubbish that supposed 'fitness influencers' are communicating to an impressionable audience and lays it down for you in an easy-to-understand and entertaining manner.
I just bought this book today and I honestly have not been able to put it down! I was surprised at how much it would resonate with me. It is definitely far more than just a diet book' (as per it's name) but has motivated me in so many other aspects of my life as well. Do yourself a favour and purchase it. You won't be disappointed!
